ASTROMOD: a computer program integrating vegetation dynamics modelling, environmental modelling and spatial data visualisation in Microsoft Excel

This paper describes the development of a software framework for predicting vegetation change within the Astroni crater, a state nature reserve near Naples, Italy. ASTROMOD (ASTROni MODel), is designed to allow the analysis of environmental and management scenarios in the crater, thus aiding the reserve's manager in effective decision making. ASTROMOD comprises a vegetation dynamics model developed for forest ecosystems, combined with models of environmental determinants. It integrates a user-friendly interface for visualising spatial data, a parameter database and a series of programming modules within Microsoft Excel. This approach is a significant departure from other spatial biophysical modelling approaches which require costly and complex software tools. (C) 2002 Elsevier Science Ltd. All rights reserved.
